Electronic filter assembly

Abstract

An electronic filter comprises a housing having input and output ends. The housing has a body and a connector. The connector is located at the input end of the housing. A circuit board is located within the body. A collet assembly is located within the connector to receive electrical signals and conduct them to the circuit board. The collet assembly includes an insulator, a conductor, and an elastomeric sealing member. The insulator is located within the connector. The insulator contains a generally cylindrical opening through its length. The conductor extends through the opening of the insulator. The conductor has an input end adjacent the input end of the housing and an output end adjacent the circuit board. The conductor has a hollow interior at its input end. The sealing member surrounds the insulator in compressed engagement with the insulator and the surrounding connector.

No. 6,323,743.BACKGROUND OF THE INVENTION [0002] 1. Technical Field [0003] The present invention relates generally to electronic filters used in the cable television industry, and relates more particularly to the construction and assembly of such filters. [0004] 2. Background Art [0005] Typical electronic filter constructions in the cable television (CATV) industry involve a considerable number of parts, such as, for example, one or more circuit boards, connecting wires or leads, filter circuit components, isolation plates, blocks or chambers, input and output terminals, moisture barrier seals or plugs, connector housings, sub-housings...

AI Technical Summary

Benefits of technology

[0012] It is therefore an object of the present invention to provide an electronic filter construction that avoids the limits and problems associated with the prior art.

[0015] It is still another object of the present invention to reduce material and labor costs associated with the assembly of an electronic filter;

[0016] It is still a further object of the present invention to reduce the size and weight of an electronic filter; and

[0017] It is still yet another object of the present invention to provide an electronic filter construction that has improved moisture resistance.

Problems solved by technology

Such an approach requires the additional parts and expense of o-rings and outer housing sleeves, and may require manual assembly of such parts.

However, such methods usually require additional components or manual assembly steps.
